Description

Technical Field

[0001] This utility model relates to the field of automated assembly line technology, and in particular to a material tray turnover mechanism for a moisture-proof sheet assembly machine. Background Technology

[0002] Automated assembly lines are generally organically integrated systems comprised of conveyor equipment and specialized equipment. They are highly automated assembly production lines based on electromechanical, information, imaging, and networking technologies. In the manufacturing process of most assembly line equipment, the processing and manufacturing of various parts usually begins first, followed by product assembly. This production model is not only applicable to the assembly line industry but also to the manufacturing processes of other products. Automated assembly lines are production equipment specifically designed for various assembly, inspection, labeling, and packaging processes in the later stages of product manufacturing.

[0003] Currently, on automated assembly lines for moisture-proof sheets, in order to automate the entire assembly process, it is often necessary to transfer the material tray from one processing station to another. This process requires the use of a material tray turnover mechanism. However, the previous generation of material tray turnover mechanisms had the following shortcomings in actual use: the original material tray turnover mechanism was equipped with a single mechanical gripper to perform the gripping, conveying, and placement of the material tray. The entire material tray turnover process was time-consuming and had poor stability. This resulted in the overall processing speed of the assembly machine needing to be adjusted according to the operating speed of the material tray turnover mechanism, reducing the efficiency and continuity of the actual assembly and processing of moisture-proof sheets.

[0004] In view of this, it is particularly important to design and manufacture a material tray turnover mechanism that can realize continuous and rapid turnover of material trays, improve the overall operating efficiency and stability of assembly machines, and apply it to automated assembly lines. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the material tray turnover mechanism of the previous generation of moisture-proof sheet assembly machine has a long turnover time and poor stability, which leads to a decrease in the working efficiency of the entire assembly machine and affects the high-efficiency assembly and processing of moisture-proof sheets. Therefore, a material tray turnover mechanism for moisture-proof sheet assembly machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A material tray turnover mechanism for a moisture-proof sheet assembly machine includes an assembly table. A recessed feeding trough is located at the center of the right end of the assembly table, and a recessed unloading trough is located on the left side of the front end of the assembly table. A tray trolley is installed below the interior of both the feeding and unloading troughs. Multiple vertically arranged material trays are stacked on the upper end of the tray trolleys. Lifting parts for vertically adjusting the stacking of the multiple material trays are provided on the inner sides of both the feeding and unloading troughs. A feeding robot is installed above the feeding trough at the upper end of the assembly table, and an unloading robot is installed above the unloading trough at the upper end of the assembly table. A material tray turnover mechanism is located between the feeding and unloading robots at the upper end of the assembly table to continuously transport the material trays from the feeding trough to the unloading trough.

[0008] As a further description of the above technical solution:

[0009] The material tray turnover mechanism includes a material tray turnover platform fixed to the upper right front of the assembly platform, a Y-axis conveying section disposed between the upper end of the assembly platform and the lower end of the material tray turnover platform for conveying material trays in the loading trough to the material tray turnover platform below the material tray turnover platform, an X-axis conveying section disposed in the middle of the lower end of the material tray turnover platform for conveying material trays in the material tray turnover platform to the unloading trough, and a top plate disposed at the lower end of the assembly platform for transferring material trays from the Y-axis conveying section to the X-axis conveying section.

[0010] As a further description of the above technical solution:

[0011] The X-axis conveying unit includes an X-axis pneumatic guide rail mounted on the upper part of the material tray turntable, a transverse slide mounted below the X-axis pneumatic guide rail, two symmetrically movable clamping jaws mounted on the left end of the transverse slide, and a double-headed cylinder mounted on the lower end of the transverse slide and located between the two clamping jaws.

[0012] As a further description of the above technical solution:

[0013] The Y-axis conveying unit includes a Y-axis pneumatic guide rail mounted on the upper part of the assembly table and located directly below the material tray turntable, a longitudinal slide mounted above the Y-axis pneumatic guide rail, a first single-head cylinder mounted in the middle of the upper part of the longitudinal slide, and a pallet frame movably mounted between the longitudinal slide and the upper part of the first single-head cylinder.

[0014] As a further description of the above technical solution:

[0015] The top plate includes a second single-head cylinder installed at the lower end of the assembly table and located directly below the material tray turnover table, a lifting frame installed at the lower end of the second single-head cylinder, and top plate pins installed at the four corners of the upper end of the lifting frame and extending upward through the assembly table.

[0016] As a further description of the above technical solution:

[0017] The lifting unit includes a Z-axis servo module installed inside the loading and unloading troughs, a lifting slide movably installed at the front end of the Z-axis servo module and facing the tray trolley, and a servo motor installed between the Z-axis servo module and the lifting slide.

[0018] As a further description of the above technical solution:

[0019] The upper end of the assembly table is equipped with pneumatic material tray clamps for limiting and fixing the material trays to each other, located between the corners of the feeding trough and the unloading trough.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, the original material tray turnover mechanism has been scientifically and rationally improved. The material tray turnover mechanism mainly consists of four parts: a material tray turnover table, an X-axis conveyor, a Y-axis conveyor, and a top plate. In actual operation, when the Y-axis conveyor works, it can move the entire pallet frame backward along the Y-axis to below the material tray and lift the material tray upward. Then, when it moves to below the material tray turnover table, the top plate can lift the material tray on the pallet frame upward. When the X-axis conveyor works, it can grab the lifted material tray and convey it towards the lower material trough. In the entire turnover process, the X-axis conveyor, Y-axis conveyor, and top plate cooperate with each other without interfering with each other. This structure can realize uninterrupted continuous grabbing, conveying, and placement of the material tray, effectively improving the speed of the entire material tray turnover operation. At the same time, the entire turnover process is less prone to material tray displacement and falling off, thereby improving the efficiency, continuity, and stability of the actual operation of the material tray turnover mechanism.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a material tray turnover mechanism for a moisture-proof sheet assembly machine, including an assembly table 1. A recessed loading trough 101 is provided at the center of the right end of the assembly table 1, and a recessed unloading trough 102 is provided on the left side of the front end of the assembly table 1. A tray trolley 4 is provided below the interior of both the loading trough 101 and the unloading trough 102. Multiple vertically distributed material trays 401 are stacked on the upper end of the tray trolley 4. The inner side of 02 is provided with a lifting part for vertical lifting and stacking adjustment of multiple material trays 401. The upper end of the assembly table 1 is equipped with a feeding robot 2 above the feeding trough 101, and the upper end of the assembly table 1 is equipped with a discharging robot 3 above the discharging trough 102. The upper end of the assembly table 1 is provided between the feeding robot 2 and the discharging robot 3, which is a material tray turnover mechanism that can continuously transport the material trays 401 in the feeding trough 101 to the discharging trough 102.

[0030] Specifically, such as Figure 1-4 As shown, the material tray turnover mechanism includes a material tray turnover platform 5 fixed to the upper right front of the assembly table 1, a Y-axis conveying section disposed between the upper end of the assembly table 1 and the lower end of the material tray turnover platform 5 for conveying the material tray 401 in the loading trough 101 to the material tray turnover platform 5 below the material tray turnover platform 5, an X-axis conveying section disposed in the middle of the lower end of the material tray turnover platform 5 for conveying the material tray 401 in the material tray turnover platform 5 to the unloading trough 102, and a top plate disposed at the lower end of the assembly table 1 for transferring the material tray 401 from the Y-axis conveying section to the X-axis conveying section.

[0031] Specifically, such as Figure 1-3As shown, the X-axis conveying unit includes an X-axis pneumatic guide rail 501 mounted on the upper end of the material tray turntable 5, a transverse slide 502 mounted below the X-axis pneumatic guide rail 501, two symmetrically movable clamping jaws 503 mounted on the left end of the transverse slide 502, and a double-headed cylinder 504 mounted on the lower end of the transverse slide 502 and located between the two clamping jaws 503. The double-headed cylinder 504 is normally in an extended state, and the two clamping jaws 503 are in an expanded state. When the transverse slide 502 moves above the material tray 401, the two clamping jaws 503 can be positioned on both sides of the material tray 401. When the double-headed cylinder 504 retracts inward, the material tray 401 can be clamped and fixed below the transverse slide 502, thereby facilitating the subsequent transverse placement operation of the material tray 401.

[0032] Specifically, such as Figure 1-3 As shown, the Y-axis conveying unit includes a Y-axis pneumatic guide rail 6 mounted on the upper end of the assembly table 1 and located directly below the material tray turntable 5; a longitudinal slide 601 mounted above the Y-axis pneumatic guide rail 6; a first single-head cylinder 602 mounted in the middle of the upper end of the longitudinal slide 601; and a pallet frame 603 movably mounted between the upper ends of the longitudinal slide 601 and the first single-head cylinder 602. When the Y-axis pneumatic guide rail 6 is working, it can drive the longitudinal slide 601 to move backward or forward along the Y-axis, realizing... In the receiving and conveying operation of the material tray 401, the first single-head cylinder 602 is normally in a retracted state. At this time, the entire pallet frame 603 can be positioned below the uppermost material tray 401 in the feeding trough 101. When the first single-head cylinder 602 extends outward, it can drive the entire pallet frame 603 to move upward, lifting the uppermost material tray 401 in the feeding trough 101 and separating it from other material trays 401, so as to facilitate the forward conveying of the material tray 401 to the area below the material tray turnover table 5.

[0033] Specifically, such as Figure 1-3 As shown, the top plate includes a second single-head cylinder 7 installed at the lower end of the assembly table 1 and located directly below the material tray turnover table 5, a lifting frame 701 installed at the lower end of the second single-head cylinder 7, and top plate pins 702 installed at the four corners of the upper end of the lifting frame 701 and extending upward through the assembly table 1. Under normal conditions, the second single-head cylinder 7 is in an extended state, at which time the top plate pins 702 on the lifting frame 701 are located below the tray frame 603. In the working state, the second single-head cylinder 7 can retract inward, driving the four top plate pins 702 to move upward, raising the material tray 401 on the tray frame 603 to below the transverse slide table 502, facilitating the subsequent clamping and placement of the material tray 401.

[0034] Specifically, such as Figure 4As shown, the lifting unit includes a Z-axis servo module 8 installed inside the loading trough 101 and unloading trough 102, a lifting slide 801 movably installed at the front end of the Z-axis servo module 8 and facing the pallet trolley 4, and a servo motor 802 installed between the Z-axis servo module 8 and the lifting slide 801. When the servo motor 802 is working, it can drive the lifting slide 801 to move up and down along the Z-axis on the Z-axis servo module 8, thereby realizing the lifting and adjustment operation of the stacking position of the material tray 401 in the loading trough 101 and unloading trough 102.

[0035] Specifically, such as Figure 1 As shown, pneumatic tray clamps 103 are installed at the upper end of the assembly table 1 between the corners of the loading trough 101 and the unloading trough 102 for limiting and fixing the material trays 401 in opposite directions. These clamps can assist in clamping the material trays 401 to be picked up at the top of the loading trough 101 and the material trays 401 placed at the top of the unloading trough 102, preventing the material trays 401 from shifting, shaking, or being inaccurately positioned, thus affecting the automated continuous turnover operation of the material trays 401.

[0036] Working principle: During use, the material trays 401 to be loaded can be stacked on the tray trolley 4 and then pushed into the loading trough 101. After receiving unloaded material, the tray trolley 4 can be pushed into the unloading trough 102. During the operation of the tray turnover mechanism, firstly, the Y-axis pneumatic guide rail 6 can insert the longitudinal slide 601 backwards under the top stacked material tray 401. Then, the first single-head cylinder 602 can extend outwards, driving the pallet frame 603. The upward movement contacts the material tray 401, then the Y-axis pneumatic guide rail 6 returns to its initial position, and the first single-head cylinder 602 retracts inward to reset. At this time, the material tray 401 taken from the loading trough 101 moves directly below the material tray turnover table 5. Next, the second single-head cylinder 7 retracts inward, and the lifting frame 701 moves upward below the assembly table 1. The four top plate pins 702 then contact the lower end of the material tray 401, aligning the material tray 401. The support bracket sits on the pallet frame 603, facilitating subsequent clamping operations by the X-axis conveyor. At this point, the Y-axis conveyor can continue with the turnover operation of the next material tray 401. Finally, the X-axis pneumatic guide rail 501 moves and adjusts the transverse slide 502 to directly above the lifted material tray 401. When the double-headed cylinder 504 retracts inward, the two clamping jaws 503 contact the side wall of the material tray 401, and then the material tray 401 is clamped onto the transverse slide 502. Below, when the material tray 401 reaches directly above the feeding trough 102 under the movement of the X-axis pneumatic guide rail 501, the servo motor 802 in the feeding trough 102 can drive the lifting slide 801 to move upward in the Z-axis servo module 8 to pick up the material tray 401 after it has been gripped. Then the X-axis conveying unit can place the material tray 401 on the lifting slide 801 to continue the subsequent gripping and conveying operations, thus completing the uninterrupted continuous turnover operation of the material tray 401.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
